A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration.
What will happen to the cell?
Choose 1 answer:
Water will move out of the cell, causing it to swell.
Water will move into the cell, causing it to shrink.
Water will move into the cell, causing it to swell.
Water will move out of the cell, causing it to shrink.
Answer:
Water will move out of the cell, causing it to shrink.
Explanation:
When something with a low salt concentration is placed in a higher concentration of salt, the salt in the solution will try to suck out the water in the cell. Just remember why we hate salt, because it sucks! There's a little joke to help u remember. Thanks, Ms. Hoj :)
Answer:
CORRECT (SELECTED)
Water will move out of the cell, causing it to shrink.
Explanation:
The cell has lower concentration of solute and a higher concentration of water than the solution it is placed in. This means that water will move out of the cell, causing it to shrink.
Explain why the forest ecosystem is a system.
Answer:
Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.
Explanation:
That is the sample answer.
Which one has higher ecosystem diversity, rain forest or desert?
Answer: The Rain forest

Now that the lab is complete, it’s time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
The lab report is composed of three sections:
Section I: Experimental Overview
o Provide background information.
o Include the hypothesis.
o Summarize the procedure.
Section II: Data & Analysis
o Include graphs to display trends in the data.
o Identify trends in the data.
Section III: Conclusions
o Identify if the hypothesis was supported or refuted.
o Provide logical reasoning based on data.
o Explain how the experiment could be improved.
To help you write your lab report, you will first answer the eight questions listed below based on the experiment that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn into your teacher.
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.
Questions
Section I: Experimental Overview
1. What is the question that you are trying to answer?
2. What is your hypothesis for this experiment?
3. What methods are you using to test this hypothesis?
Outline the steps of the procedure in full sentences.
Section II: Data & Analysis
4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following:
a. an appropriate title
b. appropriate labels for each axis
c. an appropriate scale for each axis
d. the correct units for the data
Complete a rough sketch of each graph.
5. What do the data in your graphs tell you?
Explain in one or two sentences what trend the reader should observe in each of your graphs.
Section III: Conclusions
6. What do the data tell you about your hypothesis?
State how your hypothesis is either supported OR refuted by the data.
7. How do the data support your claim above?
Explain your statement above. Be sure to refer to specific pieces of data from your experiment that support your argument.
Answer:
1. What is the purpose of the lab, the importance of the topic, and the question you are trying to answer?
Explore the process for determining the density of a solid using a laboratory procedure. The importance of the lab in the topic is to find how density of an object is and if it can sink or float and it is important to answer the question so you can also find mass and volume.
2. What is your hypothesis (or hypotheses) for this experiment?
If the mass and volume of an object can be measured, then its density can be determined, because density equals mass over volume.
The force of the Earth's gravity on an object gives the object its __________.
volume
mass
weight
density
Answer:
weight
Explanation:
The gravitational force between a mass and the Earth is the object's weight.
Answer:
Weight
Explanation:
Whe weight of an object is the force of gravity on the object and may be defined as a mass times the acceleration of gravity,w=mg.Since the weight is a force,its SI unit is the newton.

Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell. They contain all the genetic information of an organism. Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?
A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.
D)The cell cycle stops, allowing for extra haploid cells to be made.
Answer:
C
Explanation:
I am pretty sure answer is C.
Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.
What is the function of the chromosome in meiosis?The chromosomes present in the parent cell duplicate in the S phase of the cell cycle, and in the meiosis phase of the cell cycle, the daughter chromatids segregate and form four haploid cells from the parent cell. The child or offspring is the result of the fertilization of the sperm and the ovum, and the zygote is formed from the process that develops into the offspring, and the zygote has half the genetic contents of the paternal and maternal parents. In this way the chromosomes separate in the meiosis.
Hence, Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

Explanation:
I think it would be easier if u have options but I will help as much as I know abt this.. so The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology.

If I study light and dark peppered moths in light and dark environments what would be the test variable and the outcome variable?
Answer:
the independent (test) variable is the physical changes (studying in the light or the dark) and the dependent (outcome) variable would be whatever you are trying to study (I assume it is the behavior of the moths)
Explanation:
the test variable is the variable you change during the experimental process and the outcome variable is what would be directly effected by the change in the experiment.
Test Variable--- changing the amount of light
Outcome Variable--- the effect it has on the moths
